Autonomous replication

I received a few replies concerning autonomous replication in Neurospora.
Most detailed was from fons.debets*fungen.el.wau.nl who said that he had
compared transformation of N.c. with a hygromycin vector alone and in
combination with an autonomous vector. They observed NO increase in
transformation frequency in Nc, unlike the 10-100 fold increase they
observed with A. nidulans and some other fungi.
This suggests that the Aspergillus element does not function in Nc,
any other direct experience?
